Despite what many people will tell you this isn't the time to ask some carefully crafted question which will make you appear to be a better candidate. Sure, there are interviewers who believe this, but anyone who thinks that way is not someone I really want to work with anyways. Instead, this is your opportunity to fill in any blanks you might have regarding if you actually want to grace them with your presence. IMO "no" is a perfectly valid response to that question as it is possible that any question marks you had were already discussed during the interview itself. When dealing with more standard tech interviews (multiple panels of 1-2 people largely consisting of tech questions) I usually try to use that time to get a better sense of the day to day life working there from that interviewer's perspective. What do they do, how do they work, what don't they like, etc.
